title = "Solution preparation of Ge nanoparticles with chemically tailored surfaces",
abstract = "The solution preparation of Ge nanoparticles with chemically tailored surfaces was discussed. The metathesis of the Zintl salts NaGe, KGe and Mg2Ge with GeCl4 in boiling glymes was used to prepare Ge nanoparticles. Results showed that the reaction between Mg2Ge and GeCl4 in refluxing diglyme produces Ge nanoparticles in high yields and surface of these particles may be terminated using Grignard reagents.",

note = "Funding Information: The reaction between Mg 2 Ge and GeCl 4 in refluxing diglyme produced Ge nanoparticles in high yields, and the surface of these nanoparticles may be terminated using Grignard reagents. Since the particles produced by the initial metathesis reaction are from 2 to 10 nm in diameter [15,16] , from 10 to 30% of their atoms are on the surface. With such a large proportion of atoms at the surface, its termination is vital to controlling their properties. Surface termination with Grignard reagents forms a robust protective layer at the surface of the nanoparticle, and can provide an opportunity for further chemical manipulation. Though a considerable amount of work remains, chemically manipulating the surface of the nanoparticles may provide the ability to further tailor their properties and incorporate them into composite materials or devices. The ability to chemically change the surface of the nanoparticles yet retain luminescence due to quantum confinement is unique to this preparative method. This work was performed under the auspices of the US Department of Energy by University of California, Lawrence Livermore National Laboratory under contract No. W-7405-Eng-48.",
